Zak Ringelstein
Zak Ringelstein is the co-founder and CEO of Zigazoo, a moderated, kid-safe social network often described as the antidote to TikTok. A former public school teacher and Teach For America alum, he built and sold his first edtech company UClass to Renaissance Learning, ran a left-insurgent 2018 U.S. Senate campaign in Maine as the only DSA-endorsed major-party nominee, then launched Zigazoo with his wife Leah during the pandemic. The company has raised roughly $26M total, including a $17M celebrity-studded Series A, and made headlines when Australia exempted Zigazoo from its sweeping social media ban.
